Greed is a variable which might explain and predict a range of real-life criteria. Although often consulted as explanation in the public media, related scientific research has only recently begun. We approached greed from a personality psychology perspective regarding its nomological net and the prediction of theoretically related criteria. We found that a wide array of indicators, including behavior in economic games and risk games, as well as self-reported money investment and aimed at income, can be meaningfully predicted by dispositional greed, over and above the Big Five. Additionally, we found that dispositional greed is substantially related to psychopathy. According to our results, dispositional greed is an important variable which might explain unique variance with regard to theoretically related behaviors. [ABSTRACT FROM AUTHOR]

We applied trait activation theory to investigate the situational properties that moderate the correlation of intellect, a sub-dimension of the Big Five factor openness to experience, with work-related criteria. We collected data from a sample of 185 employees from diverse organizations and positions. Results from moderated hierarchical regression analyses revealed that perceived situational properties at the task level moderated the correlation between intellect and job performance. Additionally, correlations between intellect and organizational commitment were moderated at task and organizational levels. This study shows how trait activation theory can be utilized to investigate the situational properties moderating the correlation of personality variables with external criteria. Implications for applied purposes are discussed. [ABSTRACT FROM AUTHOR]

• Situations in SJTs did not or only marginally affect the construct-related validity of SJTs. • This study adds more evidence speaking to the perspective of SJTs as context-independent measures. • This study provides further evidence that experimental test validation provides interesting insights that go beyond correlative validation approaches. Despite the common belief that situation descriptions in SJTs are central to the measurement of targeted constructs, recent studies demonstrated that omitting situation descriptions had only minor effects on SJT performance and validity. However, these results might be due to the fact that traditional SJTs often fail to assess well-defined constructs. So, we aimed to examine the relationships between construct-driven SJT scores with and without situations and self- and peer-rated personality dimensions (N = 158). Results revealed almost no difference in construct-related validity between both versions. The conscientiousness facet emerged as the only exception, for which the SJT scores without situation descriptions yielded a significantly higher convergent correlation. [ABSTRACT FROM AUTHOR]
